We have become used to bogus claims made by homeopaths – far too much so, I would argue. Therefore, we let the vast majority of their bogus claims pass without serious objections. Yet exposing bogus claims would be an important task, particularly when they relate to serious conditions. Doing this might even save lives!

According to the website of the ‘HOMEOPATHIC DOCTOR’, homeopathy is mild in nature and tends to modify the body’s natural immunity. It is the responsibility of the immune system of the body to protect it from all sorts of damage, whether from bacteria or viruses or from any other disease. It also helps in repairing any damage that may occur at any time. Homeopathic medicines help strengthen the natural immunity of the body so that it can perform its natural functions in a more efficient manner.

5 Best Homeopathic remedies for Ulcerative Colitis

In my experience, homeopathic medicines like Merc Sol, Baptisia, Nux Vomica, Arsenic Album and Phosphorus have been found to be quite effective in the treatment of Ulcerative Colitis…

Merc Sol- One of the best homeopathic medicines for ulcerative colitis with blood and tenesmus

When there is too much bleeding with tenesmus and other symptoms, Merc Sol is one of the best homeopathic medicines for ulcerative colitis. There are frequent stools with blood being discharged almost every time. The patient is a sweaty sort of patient who keeps on sweating most of the time. Creeping sort of chilliness may be felt in the back.

Nux Vomica- One of the best homeopathic remedies for ulcerative colitis due to high life

When the problem has occurred from living a high life, Nux Vomica is one of the best homeopathic remedies for ulcerative colitis. Excess of alcohol, stimulants like tea and coffee, late night partying and other habits incident to modern lifestyle can contribute to such a problem. The patient is usually a chilly sort of patient who cannot tolerate cold. He is unusually angry and that too at trifles.

Arsenic Album – One of the best homeopathic medicines for ulcerative colitis with anxiety and restlesness

When the predominant symptoms are the mental symptoms of anxiety and restlessness, Arsenic Album is one of the best homeopathic medicines for ulcerative colitis. The patient gets anxious, worried and restless for no rhyme or reason. There may be weakness which may be disproportionately more than the problem. There is increased thirst for water, though the patient takes a small quantity or a sip at a time.

Baptisia – One of the best homeopathic remedy for ulcerative colitis with low grade fever

When there is low grade fever present along with other symptoms, Baptisia is one of the best homeopathic remedy for ulcerative colitis. The patient has great muscular soreness all over the body as if bruised and beaten. Appetite is reduced or next to nil. At the same time, there is constant desire for water. Stools are very offensive, thin and watery.

Phosphorus – One of the best homeopathic medicine for ulcerative colitis with increased thirst for cold water

When there is intense thirst for cold water, Phosphorus is one of the best homeopathic medicine for ulcerative colitis. The patient is usually tall and thin. The diarrhoea is copious. Stool is watery and profuse bleeding may be present. Patient feels too weak and more so after passing a stool.

The ‘HOMEOPATHIC DOCTOR’s first statement was ‘in my experience…’? Unfortunately most patients will not understand what this expression truly means when written by a homeopath. It means THERE IS NOT A JOT OF EVIDENCE FOR ANY OF THIS. Had he stated this clearly, it would probably have been the only correct sentence in the whole article.

People who understand medicine a bit might laugh at such deluded clinicians and their weird, unethical recommendations. However, patients who are chronically ill and therefore desperate might take them seriously and follow their advice. Patients who suffer from potentially life-threatening diseases like ulcerative colitis might then cause serious damage to themselves or even die.

And this is precisely the reason why I will continue to expose these charlatans for what they are: irresponsible, unethical, uninformed, dangerous quacks

This is your occasion to meet some of the most influential and progressive people in health care today! An occasion too good to be missed! The future of medicine is integrated – we all know that, of course. Here you can learn some of the key messages and techniques from the horses’ mouths. Book now before the last places have gone; at £300, this is a bargain!!!

The COLLEGE OF MEDICINE announced the event with the following words:

This two-day course led by Professor David Peters and Dr Michael Dixon will provide an introduction to integrated health and care.  It is open to all clinicians but should be particularly helpful for GPs and nurses, who are interested in looking beyond the conventional biomedical box.  

The course will include sessions on lifestyle approaches, social prescribing, mind/body therapies and cover most mainstream complementary therapies.  

The aim of the course will be to demonstrate our healing potential beyond prescribing and referral, to provide information that will be useful in discussing non-conventional treatment options with patients and to teach some basic skills that can be used in clinical practice.  The latter will include breathing techniques, basic manipulation and acupuncture, mind/body therapies including self-hypnosis and a limited range of herbal remedies.  There will also be an opportunity to discuss how those attending might begin to integrate their everyday clinical practice.  

The course will qualify for Continuing Professional Development hours and can provide a first stage towards a Fellowship of the College.

Both Dixon and Peters have been featured on this blog before. I have also commented regularly on the wonders of integrated (or was it integrative?) medicine. And I have even blogged about the College of Medicine and what it stands for. So readers of this blog know about the players as well as the issues for this event. Now it surely must be time to learn more from those who are much better placed than I to teach about bogus claims, phoney theories and unethical practices.

What are you waiting for? Book now – they would love to have a few rationalists in the audience, I am sure.

Prince Charles’s car has been involved in a collision with a deer in the area around Balmoral, THE GUARDIAN reported. Charles remained uninjured but shaken by the incident. The condition of the deer is unknown but might be much worse. The Prince’s Audi was damaged in the collision at the Queen’s Aberdeenshire estate and sent away for repairs. A spokesman for Clarence House declined to comment on the crash.

This is the story roughly as it was reported a few days ago. It is hardly earth-shattering, one might even say that it is barely news-worthy. Therefore, I thought I might sex it up a little by adding some more fascinating bits to it – pure fantasy, of course, but news-stories have been known to get embellished now and then, haven’t they?

Here we go:

As the papers rightly state, Charles was ‘shaken’, and such an acute loss of Royal well-being cannot, of course, be tolerated. This is why his aids decided to make an urgent telephone call to his team of homeopaths in order to obtain professional and responsible advice as to how to deal with this precarious situation. This homeopathic team discussed the case for about an hour and subsequently issued the following consensual and holistic advice:

  • Scrape some hair or other tissue of the deer from the damaged car.
  • Put it in an alcohol/water mixture.
  • Take one drop of the ‘mother tincture’ and put it in 99 drops of water.
  • Shake vigorously by banging the container on a leather-bound bible.
  • Take one drop of the resultant mixture and put it in 99 drops of water.
  • Shake vigorously by banging the container on a leather-bound bible.
  • Repeat this procedure a total of 30 times.
  • This generates the desired C30 remedy.
  • Administer 10 drops of it to the Prince by mouth.
  • Repeat the dose every two hours until symptoms subside.

The Prince’s loyal aids followed these instructions punctiliously, and after 24 hours the Prince’s anxiety had all but disappeared. Upon hearing the good news, the homeopaths were delighted and instructed to discontinue the ‘rather potent’ remedy. Now they plan to publish the case in Peter Fisher’s journal ‘Homeopathy’.

The Prince showed himself even more delighted and told a reporter that he “had always known how incredibly powerful homeopathy is.” He added that he has already written to Health Secretary Hunt about homeopathy on the NHS, “it is high time that the NHS employs more homeopathy”, Charles said, “it would save us all a lot of money and might even solve the NHS’s current financial problems with one single stroke.”

The Faculty of Homeopathy is preparing a statement about this event, and the homeopathic pharmacy Ainsworth allegedly is considering marketing a new range of remedies called ROADKILL. The Society of Homeopaths feels somewhat left out but stated that “homeopathy is very powerful and should really be in the hands of professional homeopaths.” A group of homeopathic vets declared that they could have saved the deer, if they had had access to the animal and added “homeopathy works in animals, and therefore it cannot be a placebo.”

Everyone at Balmoral and beyond seems reasonably happy (perhaps not the deer). However, this does not include the local car mechanics charged with the repair of the Audi. They were reported to lack empathy and knowledge about ‘integrative, holistic body work’. Their opposition to following orders went as far as refusing to repair the car according to homeopathic principles: sprinkling ‘Deer C30’, as the new remedy is now called, on the car’s bonnet.

This recent report is worth a mention, I think:

The Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) is aware that some chiropractors are advertising and attempting to turn breech babies in utero using the “Webster Technique”.

On 7 March 2016, the Chiropractic Board of Australia released the following statement in relation to chiropractic care of pregnant women and their unborn child:

“Care of pregnant patients

Chiropractors are not trained to apply any direct treatment to an unborn child and should not deliver any treatment to the unborn child. Chiropractic care must not be represented or provided as treatment to the unborn child as an obstetric breech correction technique.

RANZCOG supports the Chiropractic Board of Australia in its clear position that chiropractic care must not be represented or provided as a treatment to the unborn child as an obstetric breech correction technique. Chiropractors should not be using the “Webster Technique” or any other inappropriate breech correction technique to facilitate breech version as there is insufficient scientific evidence to support this practice.

In addition, RANZCOG does not support chiropractors treating pregnant women to reduce their risk of caesarean delivery. There is insufficient evidence to make any claims to consumers regarding the benefits of chiropractic treatment to reduce the risk of caesarean delivery. We commend the Chiropractic Board on their statement that:

“Advertisers must ensure that any statements and claims made in relation to chiropractic care are not false, misleading or deceptive or create an unreasonable expectation of beneficial treatment.”1

Recommendations for the management of a breech baby at term are outlined in the RANZCOG statement, Management of breech presentation at term

External Cephalic Version (ECV) is a procedure where a care provider puts his or her hands on the outside of the mother’s belly and attempts to turn the baby from breech to cephalic presentation. It is recommended that women with a breech presentation at or near term should be informed about external cephalic version (ECV) and offered it if clinically appropriate. Attempting cephalic version at term reduces the chance of non-cephalic presentation at birth, vaginal cephalic birth not achieved and caesarean section. There is not enough evidence from randomised trials to assess complications of ECV at term. Large observational studies suggest that complications are rare. ECV should only be performed by suitably trained health professionals where there is facility for emergency caesarean section. Each institution should have its own documented protocol for offering and performing ECVs.

This communiqué highlights the need for patients to be adequately informed when making health care choices.

END OF QUOTE

These are clear and badly needed words. As we have discussed often on this blog, chiropractors make all sorts of bogus claims. Those directed at children and unborn babies are perhaps the most nonsensical of them all. I applaud the College for their clear statements and hope that other institutions follow this example.

Chiropractors may not be good at treating diseases or symptoms, but they are certainly good at promoting their trade. As this trade hardly does more good than harm, one could argue that chiropractors are promoting bogus and potentially harmful treatments to fill their own pockets.

Does that sound too harsh? If you think so, please read what Canadian researchers have just published:

This study aimed to investigate the presence of critiques and debates surrounding efficacy and risk of Spinal Manipulative Therapy (SMT) on the social media platform Twitter. Specifically, it examined whether there is presence of debate and whether critical information is being widely disseminated.

An initial corpus of 31,339 tweets was compiled through Twitter’s Search Application Programming Interface using the query terms “chiropractic,” “chiropractor,” and “spinal manipulation therapy.” Tweets were collected for the month of December 2015. Post removal of tweets made by bots and spam, the corpus totalled 20,695 tweets, of which a sample (n=1267) was analysed for sceptical or critical tweets.

The results showed that there were 34 tweets explicitly containing scepticism or critique of SMT, representing 2.68% of the sample (n=1267). As such, there is a presence of 2.68% of tweets in the total corpus, 95% CI 0-6.58% displaying explicitly sceptical or critical perspectives of SMT. In addition, there are numerous tweets highlighting the health benefits of SMT for health issues such as attention deficit hyperactivity disorder (ADHD), immune system, and blood pressure that receive scant critical attention. The presence of tweets in the corpus highlighting the risks of “stroke” and “vertebral artery dissection” is also minute (0.1%).

The authors drew the following conclusions: In the abundance of tweets substantiating and promoting chiropractic and SMT as sound health practices and valuable business endeavors, the debates surrounding the efficacy and risks of SMT on Twitter are almost completely absent. Although there are some critical voices of SMT proving to be influential, issues persist regarding how widely this information is being disseminated.

I have no doubt that this paper will be sharply criticised by chiropractors, other manipulators and lobbyists of quackery. Yet I think it is an interesting and innovative approach to describe what is and is not being said on public media. The fact that chiropractors hardly ever publicly criticise or challenge each other on Twitter or elsewhere for even the most idiotic claims is, in my view, most telling.

Few people would doubt that such platforms have become hugely important in forming public opinions, and it seems safe to assume that consumers views about SMT are strongly influenced by what they read on Twitter. If we accept this position, we also have to concede that Twitter et al. are a potential danger to public health.

The survey is, however, not flawless, and the authors are the first to point that out: Given the nature of Twitter discussions and the somewhat limited access provided by Twitter’s API, it can be challenging to capture a comprehensive collection of tweets on any topic. In addition, other potential terms such as “chiro” and “spinal adjustment” are present on Twitter, which may produce datasets with somewhat different results. Finally, although December 2015 was chosen at random, there is nothing to suggest that other time frames would be significantly similar or different. Despite these limitations, this study highlights the degree to which discussions of risk and critical views on efficacy are almost completely absent from Twitter. To this I would add that a comparison subject like nursing or physiotherapy might have been informative, and that somehow osteopaths have been forgotten in the discussion.

The big question, of course, is: what can be done about creating more balance on Twitter and elsewhere? I wish I had a practical answer. In the absence of such a solution, all I can offer is a plea to everyone who is able of critical thinking to become as active as they can in busting myths, disclosing nonsense and preventing the excesses of harmful quackery.

Let’s all work tirelessly and effectively for a better and healthier future!

WARNING: THIS MIGHT MAKE YOU LAUGH OUT LOUDLY AND UNCONTROLLABLY.

Deepak Chopra rarely publishes in medical journals (I suppose, he has better things to do). I was therefore intrigued when I saw a recent article of which he is a co-author.

The ‘study‘ in question allegedly examined the effects of a comprehensive residential mind–body program on well-being. The authors describe it as “a quasi-randomized trial comparing the effects of participation in a 6-day Ayurvedic system of medicine-based comprehensive residential program with a 6-day residential vacation at the same retreat location.” They included 69 healthy women and men who received the Ayurvedic intervention addressing physical and emotional well-being through group meditation and yoga, massage, diet, adaptogenic herbs, lectures, and journaling. Key components of the program include physical cleansing through ingestion of herbs, fiber, and oils that support the body’s natural detoxification pathways and facilitate healthy elimination; two Ayurvedic meals daily (breakfast and lunch) that provide a light plant-based diet; daily Ayurvedic oil massage treatments; and heating treatments through the use of sauna and/or steam. The program includes lectures on Ayurvedic principles and lifestyle as well as lectures on meditation and yoga philosophy. The study group also participated in twice-daily group meditation and daily yoga and practiced breathing exercises (pranayama) as well as emotional expression through a process of journaling and emotional support. During the program, participants received a 1-hour integrative medical consultation with a physician and follow-up with an Ayurvedic health educator.

The control group simply had a vacation without any of the above therapies in the same resort. They were asked to do what they would normally do on a resort vacation with the additional following restrictions: they were asked not to engage in more exercise than they would in their normal lifestyle and to refrain from using La Costa Resort spa services. They were also asked not to drink ginger tea or take Gingko biloba during the 2 days before and during the study week.

Recruitment was via email announcements on the University of California San Diego faculty and staff and Chopra Center for Wellbeing list-servers. Study flyers stated that the week-long Self-Directed Biological Transformation Initiative (SBTI) study would be conducted at the Chopra Center for Wellbeing, located at the La Costa Resort in Carlsbad, California, in order to learn more about the psychosocial and physiologic effects of the 6-day Perfect Health (PH) Program compared with a 6-day stay at the La Costa Resort. The study participants were not blinded, and site investigators and study personnel knew to which group participants were assigned.

Participants in the Ayurvedic program showed significant and sustained increases in ratings of spirituality and gratitude compared with the vacation group, which showed no change. The Ayurvedic participants also showed increased ratings for self-compassion as well as less anxiety at the 1-month follow-up.

The authors arrived at the following conclusion: Findings suggest that a short-term intensive program providing holistic instruction and experience in mind–body healing practices can lead to significant and sustained increases in perceived well-being and that relaxation alone is not enough to improve certain aspects of well-being.

This ‘study’ had ethical approval from the University of California San Diego and was supported by the Fred Foundation, the MCJ Amelior Foundation, the National Philanthropic Trust, the Walton Family Foundation, and the Chopra Foundation. The paper’s first author is director of research at the Chopra Foundation. Deepak Chopra is the co-founder of The Chopra Center for Wellbeing.

Did I promise too much?

Isn’t this paper hilarious?

Just for the record, let me formulate a short conclusion that actually fits the data from this ‘study’: Lots of TLC, attention and empathy does make some people feel better.

This is hardly something one needs to write home about; and certainly nothing to do a study on!

But which journal would publish such unadulterated advertising?

On this blog, I have mentioned the JACM several times before. Recently, I wrote about the new man in charge of it. I concluded stating WATCH THIS SPACE.

I think the wait is now over – this paper is from the latest issue of the JACM, and I am sure we all agree that the new editor has just shown us of what he is made and where he wants to take his journal.

Just as I thought that this cannot get any better, it did! It did so in the form of a second paper which is evidently reporting from the same ‘study’. Here is its abstract unaltered in its full beauty:

The effects of integrative medicine practices such as meditation and Ayurveda on human physiology are not fully understood. The aim of this study was to identify altered metabolomic profiles following an Ayurveda-based intervention. In the experimental group, 65 healthy male and female subjects participated in a 6-day Panchakarma-based Ayurvedic intervention which included herbs, vegetarian diet, meditation, yoga, and massage. A set of 12 plasma phosphatidylcholines decreased (adjusted p < 0.01) post-intervention in the experimental (n = 65) compared to control group (n = 54) after Bonferroni correction for multiple testing; within these compounds, the phosphatidylcholine with the greatest decrease in abundance was PC ae C36:4 (delta = -0.34). Application of a 10% FDR revealed an additional 57 metabolites that were differentially abundant between groups. Pathway analysis suggests that the intervention results in changes in metabolites across many pathways such as phospholipid biosynthesis, choline metabolism, and lipoprotein metabolism. The observed plasma metabolomic alterations may reflect a Panchakarma-induced modulation of metabotypes. Panchakarma promoted statistically significant changes in plasma levels of phosphatidylcholines, sphingomyelins and others in just 6 days. Forthcoming studies that integrate metabolomics with genomic, microbiome and physiological parameters may facilitate a broader systems-level understanding and mechanistic insights into these integrative practices that are employed to promote health and well-being.

Now that I managed to stop laughing about the first paper, I am not just amused but also puzzled by the amount of contradictions the second article seems to cause. Were there 65 or 69 individuals in the experimental group? Was the study randomised, quasi-randomised or not randomised? All of these versions are implied at different parts of the articles. It turns out that they randomised some patients, while allocating others without randomisation – and this clearly means the study was NOT randomised. Was the aim of the study ‘to identify altered metabolomic profiles following an Ayurveda-based intervention’ or ‘to examine the effects of a comprehensive residential mind–body program on well-being’?

I am sure that others will find further contradictions and implausibilites, if they look hard enough.

The funniest inconsistency, in my opinion, is that Deepak Chopra does not even seem to be sure to which university department he belongs. Is it the ‘Department of Family Medicine and Public Health, University of California, San Diego, La Jolla, CA.’ as indicated in the 1st paper or is it the ‘Department of Family and Preventive Medicine, University of California San Diego, La Jolla, California, USA’ as listed in the 2nd article?

Does he know from which planet he is?

 

Low back pain (LBP) is a ‘minor complaint’ in the sense that it does not cost patients’ lives. At the same time, LBP is amongst the leading causes of disability and one of the most common reasons for patients to seek primary care. Chiropractors, osteopaths, physical therapists and general practitioners are among those treating LBP patients, but there is only limited evidence regarding the effectiveness offered by these provider groups.

The aim of this systematic review was to estimate the clinical effectiveness and to systematically review economic evaluations of chiropractic care compared to other commonly used approaches among adult patients with non-specific LBP.

A comprehensive search strategy was conducted to identify 1) pragmatic randomized clinical trials (RCTs) and/or 2) full economic evaluations of chiropractic care for low back pain compared to standard care delivered by other healthcare providers. Studies published between 1990 and 4th June 2015 were considered. The primary outcomes included pain, functional status and global improvement. Study selection, critical quality appraisal and data extraction were conducted by two independent reviewers. Data from RCTs with low risk of bias were included in a meta-analysis to determine estimates of effect sizes. Cost estimates of full economic evaluations were converted to 2015 USD and results summarized.

Six RCTs and three full economic evaluations were included. Five RCTs with low risk of bias compared chiropractic care to exercise therapy (n = 1), physical therapy (n = 3) and medical care (n = 1). The authors found similar effects for chiropractic care and the other types of care. Three low to high quality full economic evaluations studies (one cost-effectiveness, one cost-minimization and one cost-benefit) compared chiropractic to medical care. Highly divergent conclusions (favours chiropractic, favours medical care, equivalent options) were noted for economic evaluations of chiropractic care compared to medical care.

The authors drew the following conclusions: moderate evidence suggests that chiropractic care for LBP appears to be equally effective as physical therapy. Limited evidence suggests the same conclusion when chiropractic care is compared to exercise therapy and medical care although no firm conclusion can be reached at this time. No serious adverse events were reported for any type of care. Our review was also unable to clarify whether chiropractic or medical care is more cost-effective. Given the limited available evidence, the decision to seek or to refer patients for chiropractic care should be based on patient preference and values. Future studies are likely to have an important impact on our estimates as these were based on only a few admissible studies.

This is a thorough and timely review. Its results are transparent and clear, however, its conclusions are, in my view, more than a little odd.

Let me try to re-formulate them such that they are better supported by the actual data: There is no good evidence to suggest that chiropractic care is better or worse that conventional therapeutic approaches currently used for LBP. The pooled sample size dimensions too small to allow any statements about the risks of the various approaches. The data are also too weak for any pronouncements on the relative cost-effectiveness of the various options. Given these limitations, the decision which approach to use should be based on a more comprehensive analysis of the therapeutic risks.

The point I am trying to make is quite simple:

  • The fact that RCTs fail to show adverse effects could be due to the small collective sample size and/or to the well-known phenomenon that, in well-controlled trials, adverse effects tend to be significantly rarer than in routine care.
  • Hundreds of serious adverse events have been reported after chiropractic spinal manipulations; to these we have to add the fact that ~50% of all chiropractic patients suffer from transient, mild to moderate adverse effects after spinal manipulations.
  • If we want to generate a realistic picture of the safety of a therapy, we need to include case-reports, case-series and other non-RCT evidence.
  • Conventional treatments of LBP may not be free of adverse effects, but some are relatively safe.
  • It seems reasonable, necessary and ethical to consider a realistic picture of the relative risks when deciding which therapy amongst equally (in)effective treatments might be best.

To me, all this seems almost painfully obvious, and I ask myself why the authors of this otherwise sound review failed to consider such thoughts. As one normally is obliged to, the authors included a section about the limitations of their review:

Our review has limitations. First, we did not search the grey literature for clinical effectiveness studies. McAuley et al. showed that the inclusion of results from the grey literature tend to decrease effectiveness estimates in meta-analyses because the unpublished studies tend to report smaller treatment effects. Second, critical appraisal requires scientific judgment that may vary among reviewers. This potential bias was minimized by training reviewers to use a standardized critical appraisal tool and using a consensus process among reviewers to reach decisions regarding scientific admissibility. Most of the original between-group differences and pooled estimates in our meta-analysis did not favour a specific provider group, and we believe it is unlikely that the inclusion of unpublished grey literature would change our conclusions. Third, the low number of clinical trials prevents us from conducting a meaningful investigation for publication bias. Fourth, the majority of the included clinical effectiveness studies (three out of five) and all three economic evaluations were conducted in the United States. Caution should therefore be used when generalizing our findings to other settings or jurisdictions. With respect to economic evaluations in particular, local healthcare systems and insurance plans may have a higher impact on cost than the type of healthcare provider.

Remarkably, this section does not mention their useless assessment of the risks with one word. Why? One answer might be found in the small-print of the paper:

After > 200 years of existence, homeopathy still remains unproven – in fact, most rational thinkers would call it disproven. Today only homeopaths doubt this statement; they work hard to find a water-tight proof that might show the doubters to be wrong.

What is better suited for this purpose than a few rigorous animal experiments?

Engystol® is a popular homeopathic product promoted as an anti-viral agent manufactured by Heel GmbH, Baden-Baden, Germany. In several in vivo and in vitro studies, it apparently affected an immune response. This new study was to “evaluate the innate and adaptive immuno-modulatory effects of oral Engystol® (1 or 10 tablets/L water consumed), prior to and post antigenic challenge in a mouse model with a well-characterized and clinically measureable immune system.”

The investigators first evaluated the murine immune response when oral Engystol® was given alone for 28 days. to mice. The animals were then challenged with an antigen-specific H5N1 HA vaccine while on Engystol® for an additional 33 days. Serum and supernatants from cultured splenic lymphocytes were collected and screened with a 32-cytokine panel. Serum vaccine epitope-specific IgG titers plus T cell and B cell phenotypes from splenic tissue were also evaluated.

The results showed that Engystol® alone did not alter immunity. However, upon vaccine challenge, Engystol® decreased CD4+/CD8+ ratios, altered select cytokines/chemokines, and anti-H5N1 HA IgG titers were increased in the group of mice receiving 10 tablet/L.

The authors concluded that “these data suggest that Engystol® can modulate immunity upon antigenic challenge.”

Engystol is being advertised as “a homeopathic preparation which has been scientifically proven to significantly reduce the duration and severity of symptoms during an acute viral infection and help protect from subsequent infections.” I was unable find good evidence for this claim and therefore have to assume that it is bogus. The only human trial I was able to locate was this one:

OBJECTIVE:

To compare the effects of a complex homeopathic preparation (Engystol; Heel GmbH, Baden-Baden, Germany) with those of conventional therapies with antihistamines, antitussives, and nonsteroidal antiinflammatory drugs on upper respiratory symptoms of the common cold in a setting closely related to everyday clinical practice.

DESIGN:

Nonrandomized, observational study over a treatment period of maximally two weeks.

SETTING:

Eighty-five general and homeopathic practices in Germany.

PARTICIPANTS:

Three hundred ninety-seven patients with upper respiratory symptoms of the common cold.

INTERVENTIONS:

Engystol-based therapy or common over-the-counter treatments for the common cold. Patients receiving this homeopathic treatment were allowed other short-term medications, but long-term use of analgesics, antibiotics, and antiinflammatory agents was not permitted. Patients were allowed nonpharmacological therapies such as vitamins, thermotherapies, and others.

MAIN OUTCOME MEASURES:

The effects of treatment were evaluated on the variables fatigue, sensation of illness, chill/tremor, aching joints, overall severity of illness, sum of all clinical variables, temperature, and time to symptomatic improvement.

RESULTS:

Both treatment regimens provided significant symptomatic relief, and this homeopathic treatment was noninferior in a noninferiority analysis. Significantly more patients (P < .05) using Engystol-based therapy reported improvement within 3 days (77.1% vs 61.7% for the control group). No adverse events were reported in any of the treatment groups.

CONCLUSION:

This homeopathic treatment may be a useful component of an integrated symptomatic therapy for the common cold in patients and practitioners choosing an integrative approach to medical care.

Let me comment on the human study first. It is an excellent example of the bias that can be introduced by non-randomization. The patients in the homeopathic group obviously were those who chose to be treated homeopathically. Consequently they had high expectations in this therapy. Consequently they reported better results than the control group. In other words the reported outcomes have nothing to do with the homeopathic remedy.

But what about the animal study? Animals, we hear so often, do not exhibit a placebo response. Does that render this investigation any more reliable?

The answer, I am afraid is no.

The animal study in question had no control group at all. Therefore a myriad of factors could have caused the observed result. This study is very far from a poof of homeopathy!

But even if the findings of the two studies had not been the result of bias and confounding, I would be more than cautious about viewing them as anything near conclusive. The reason lies in the nature of this particular homeopathic remedy.

Engystol® contains Vincetoxicum hirundinaria (D6), Vincetoxicum hirundinaria (D10), Vincetoxicum hirundinaria (D30), sulphur (D4) and sulphur (D10). In other words, it is one of those combination remedies which are not sufficiently dilute to be devoid of active molecules. Sulphur D4, for instance, means that the remedy contains one part of sulphur in 10 000 parts of diluent. It is conceivable, even likely that such a concentration might affect certain immune parameters, I think.

And my conclusion from all this?

The proof of homeopathy – if it ever came – would need to be based on investigations that are more rigorous than these two rather pathetic studies.

At first, I thought this survey would be yet another of those useless and boring articles that currently seem to litter the literature of alternative medicine. It’s abstract seemed to confirm my suspicion: “Fifty-two chiropractors in Victoria, Australia, provided information for up to 100 consecutive encounters. If patients attended more than once during the 100 encounters, only data from their first encounter were included in this study. Where possible patient characteristics were compared with the general Australian population…” But then I saw that the chiropractors were also asked to record their patients’ main complaints. That, I thought, was much more interesting, and I decided to do a post that focusses on this particular point.

The article informs us that 72 chiropractors agreed to participate (46 % response rate of eligible chiropractors approached). During the study, 20 (28 %) of these chiropractors withdrew and did not provide any data. Fifty two chiropractors (72 % of those enrolled) completed the study, providing information for 4464 chiropractor-patient encounters. Of these, 1123 (25 %) encounters were identified as repeat patient encounters during the recording period and were removed from further analyses, leaving 3287 unique patients.

The results that I want to focus on indicated that chiropractors give the following reasons for treating patients:

  • maintenance: 39%
  • spinal problems: 33%
  • neck problems: 18%
  • shoulder problems: 6%
  • headache: 6%
  • hip problems: 3%
  • leg problems: 3%
  • muscle problems: 3%
  • knee problems: 2%

(the percentage figures refer to the percentages of patients with the indicated problem)

Yes, I know, there is lots to be criticised about the methodology used for this survey. But let’s forget about this for the moment and focus on the list of reasons or indications which these chiropractors give for treating patients. For which of these is there enough evidence to justify this decision and the fees asked for the interventions? Here is my very quick run-down of the evidence:

  • maintenance: no good evidence.
  • spinal problems: if they mean back pain by this nebulous term, an optimist might grant that there is some promising but by no means conclusive evidence.
  • neck problems: again some promising but by no means conclusive evidence.
  • shoulder problems: no good evidence.
  • headache: again some promising but by no means conclusive evidence
  • hip problems: no good evidence.
  • leg problems: no good evidence.
  • muscle problems: no good evidence.
  • knee problems: no good evidence.

As I said, this is merely a very quick assessment. I imagine that many chiropractors will disagree with it – and I invite them to present their evidence in the comments section below. However, if I am correct (or at least not totally off the mark), this new survey seems to show that most of the things these chiropractors do is not supported by good evidence. One could be more blunt and phrase this differently:

  • these chiropractors are misleading their patients;
  • they are not behaving ethically;
  • they are not adhering to EBP.

Yes, we (I mean rationalists who know about EBM) did suspect this all along – but now we can back it up with quite nice data from a recent survey done by chiropractors themselves.

I have moaned about the JACM several times on this blog (for instance here). It is a very poor journal, in my view, but it nevertheless is important because it is the one with the highest impact factor in this field. Despite all this I missed something important that recently happened to the JACM: a few months ago, it got a new editor in chief: John Weeks.

Had I been more attentive, I would have known this already in May when Weeks wrote in the HuffPo this: “I was asked a month ago, out of the blue, if I would like to become editor-in-chief of the first peer-reviewed, indexed journal in what is now the “integrative health and medicine” field. The journal was born 20 years ago when — as my father would have put it — “integrative medicine” was hardly a gleam in anyone’s eye. The publication is the Journal of Alternative and Complementary Medicine.”

I have a vague memory of meeting him once at a conference and sitting next to him during a dinner. For those who haven’t heard of him, here is how he once described himself:

I have been involved as an organizer-writer in the emerging fields of complementary, alternative and integrative medicine since 1983. Happily, I have learned some things. I was once called an “expert in alternative medicine” by Medical Economics and later an “alternative care (integration) expert” by Modern Healthcare. The name-calling was proud-making, even if I was so-dubbed by reporters who were on their first forays into the field.

Both anointed me before I went on sabbatical in Costa Rica and later Nicaragua with my family in 2002. Part of the reason for sabbatical was that whatever expertise I may have developed often ran frustratingly short of being able to offer robust, successful business models with readers and clients. More than once I counseled people against the initiatives they planned. Trends taught me to recognize the invisible handwriting of a sure failure event behind the bubbling enthusiasm of an initiate. I needed a break from the work. My family and I took it!

I was away from the United States for three years. I had my hand back in things for the last 2.5 years. I assisted a philanthropist on her integrative medicine investments in community clinics, CAM schools and academic health centers. From early 2004 forward, and out of home offices in Monteverde, Costa Rica, and then Granada, Nicaragua, I helped organize and direct the National Education Dialogue to Advance Integrated Health Care: Creating Common Ground

Is Weeks going to be a good editor who throws out all the trash that JACM has been publishing on a far too regular basis? Well, the good news, I suppose, is that he cannot possibly be worse than his predecessor. Perhaps we should see for ourselves what the new man thinks and writes. Here is an excerpt from his recent editorial on the question of medical errors in conventional medicine and the role of integrative medicine in this difficult issue:

[A] whole-system solution to medical errors suggests many roles for traditional, alternative, complementary, and integrative approaches and practices. First, better use of these new therapies and provider types expands the tools and strategies for keeping the locus of care out in communities instead of in the problematic hospital environment. One of the commentators at Medscape for instance pointed out that when it comes to “errors” that lead to death, the most significant culprits are the errors individuals make in living the standard U.S. life-style. A starting place in limiting medical deaths is for us to take better care of ourselves. We’ll be less likely to need treatment or to be admitted if we do. The across-the-board engagement by multiple integrative and traditional medicine practitioners with life-style medicine, there are clearly important roles for integrative and traditional practices and practitioners.

More evidence that integrative practice keeps people healthy and out of hospitals would be useful. Our research needs to capture these life-changing outcomes better. The values movement is toward primary care and community medicine. Outpatient care offers a home-field advantage for traditional medical systems and licensed integrative health practitioners, from yoga and massage therapists to acupuncture and Oriental medicine specialists and integrative, chiropractic, and naturopathic doctors. And when people are admitted to hospitals, broader integrative teams need to be available to catch, hold, and treat the whole person and help keep them from being biomedically reduced. Such efforts would be served by research data that measure quadruple-aim outcomes. Think patient experience, enhancing life-style skills, faster healing times, diminished hospital stays, and more pleasure of practitioners in their caregiving. Some have begun gathering these outcomes. We need bushels more. We’ll also have a growing need for reports that delineate processes and obstacles overcome in highly functioning integrative care teams.

The whole-system response to medical deaths is opening minds and doors to integrative practices and to leadership from the integrative community. In one remarkable example, the state of Oregon is seeking to reduce the morbidity and mortality associated with opioids through prioritizing the care of chiropractors, acupuncturists, and massage and yoga therapists. To maximize our effectiveness as agents of change in helping create health in those we serve, more of us need to study up on the emerging language, goals, and methods of the value-based movement, then match up to these aims in our study designs and selections of outcomes. Advancing whole-person care and linking to the emerging values appear to be our best opportunities to help shape the path away from death and toward safety and health.

Impressed? Me neither!

In my view, this reads like an accumulation of platitudes, wishful thinking and uncritical waffling. The passage that I found positively worrying was this one: More evidence that integrative practice keeps people healthy and out of hospitals would be useful. Our research needs to capture these life-changing outcomes better. The editor of a medical journal should, I think, know that research is not for confirming beliefs but for testing hypotheses. In all this verbose rambling, I really cannot find a good reason why integrative medicine might have a role in reducing medical errors. More worrying still, I cannot find a trace of critical thinking.

As I was writing this, I remembered more about the only personal encounter I had with Weeks years ago. For some reason we talked about THE ‘textbook’ of naturopaths, entitled THE TEXTBOOK OF NATURAL MEDICINE. I remember explaining to Weeks that it contained a lot of factual errors and outright nonsense. He very much disputed my view, seemed to take it personally, and even got quite stroppy. In the end, we agreed to disagree.

Neither this episode nor indeed the editorial are all that important – we will simply have to wait and see how the JACM does under its new editor.
